First, choose suitable varieties according to local conditions.

Vegetable production in autumn is characterized by high temperature, less rainfall and frequent pests and diseases. Varieties should choose excellent varieties with disease resistance, high temperature resistance and high yield.

1. Cabbages: refined and improved Qingza No.3 Chinese Cabbage, Yihe Autumn Chinese Cabbage, etc.

2. Cabbages: Shuanghuanwang Cabbage, Jingfeng 1 Cabbage, etc.

3. Carrots: Please choose five-inch carrots from Kuroda;

4. Autumn cucumber: Boxin 525 green cucumber, Jin Yan series cucumber, etc.

5, lettuce: all kinds of summer lettuce, Bai Sheng Dakong lettuce;

6. Beans: Gankang 1, Gaoyou 4, Touwang Chaochang 2, preferably Ganqiuhong beans;

7. Red cabbage moss: Hong Xiang 1, Hong Xiang No.2 red cabbage moss;

8. White radish: early-maturing short leaves 13, Ma Erzao, Nanpanzhou white radish;

9. Others: Zhuzhou Xiaolong cabbage moss, etc.

Vegetable varieties suitable for autumn planting:

Chrysanthemum: There are few pests and diseases, and the growth period is short, so it is generally unnecessary to carry out pest control.

Radish: Radish has a short growth period and belongs to the type of fast lettuce. The main varieties are cherry radish.

Fennel: It usually takes more than 50 days to sow in the open field.

Rapeseed: Rapeseed is a fast-growing leafy vegetable, which has two varieties: Qingbaibang and Baibang. Its growth period is short, from planting to harvest about 40 days.

Beans: beans can be planted in spring, summer and autumn all over the south of China, with a long growth period; Suitable varieties must be selected according to the climatic conditions of each season.

Bitter gourd: It likes high temperature and sunny climate. About 50 ~ 60 days after planting, the fruit is full of tumor-like grains and tendons, and can be harvested when the peel is smooth.

Second, clean up the vegetable garden and get ready for autumn sowing.

1. Remove the diseased plants, residual leaves and rotten roots of the previous crop vegetables in time, dig the baked soil deeply, and disinfect each mu with quicklime100-150kg to reduce the occurrence base of pests and diseases.

2. Dredge the ditches, so that the "surrounding ditch, main ditch and branch ditch" can be connected, and water can be poured at any time when necessary, and discharged in time after the rain, so as not to be waterlogged.

3. Kandelia fruit vegetables must be rotated with cruciferous vegetables, onion and garlic vegetables and leguminous vegetables to reduce the occurrence and spread of various diseases.

4. Apply sufficient base fertilizer, 4000-5000 kg organic fertilizer, imported compound fertilizer 100 kg phosphate fertilizer per mu. Note: The temperature is high in summer and autumn, so try to apply less compound fertilizer to prevent burning roots and buds, which will affect the normal growth of vegetables.

Third, clean the seedbed and sow in time.

1. Sandy or cohesive soil must be selected, deep-turned, baked and raked, and the seedbed soil should be detoxified with quicklime or disinfected with 70% Dixon1000-1500 times solution.

2. Before sowing 10- 15 days, apply decomposed human and animal manure, wet and thoroughly water when sowing, set up a sunshade, cover the seeds with thin silt or plant ash after sowing, and cover them with a multi-layer sunshade net or insect-proof net. After the seedlings are unearthed, water and spray pesticides in time to keep the normal growth of the seedlings.

Details of sowing date of autumn sowing vegetables:

Beans: July1May-August10;

Cabbage: early July-early August;

Chinese cabbage: the first half of August;

White radish: early to late August;

Carrots: from late July to early August;

Lettuce: early to late August;

Red cabbage moss: early August;

Cabbage moss: early August.

Four, the main points of autumn vegetable planting

1. Because the temperature fluctuates greatly in autumn, it is suggested to mainly choose varieties with wide adaptability, cold resistance and disease resistance and high yield, such as radish and Chinese cabbage.

We should master the sowing time and avoid sowing too early or too late. Generally speaking, carrots are planted around the high temperature in summer, and radishes and Chinese cabbages are planted around beginning of autumn.

3. Pay attention to drainage and flood prevention. Because autumn sowing vegetables are hot and rainy in the early stage and low temperature and drought in the later stage, high ridge cultivation or high ridge cultivation can be used in soil preparation.

Autumn vegetables must be prevented in time, because autumn sowing vegetables are at the peak of the occurrence of Plutella xylostella, Pieris rapae and bacterial wilt. Properly strengthen field management and timely intertillage and weed control.
